I think topologically I have only those: 

  1. Mouth to ass (oh yeah)
  2. Left nostril 
  3. Right nostril 
  4. Left Eustachian tube
  5. Right Eustachian tube 
  6. Right tear duct 
  7. Left tear duct

No piercings or anything, so that's it.

Nostrils and mouth are connected, topologically you could therefore have ass to left nostril with the mouth being an own opening!

That said I really really hope you forgot your uthera at least. Which is a curious question back to the subject: is it a topological hole if the opening is only to the insides of the corpus? (Thinking about the reproductive parts of either sex specifically).

I think topologically they don't count, that's why I didn't count the urether/urethra.

is the ok symbol 👌 a hole?

what about membranes, pores?

[–] NachBarcelona@piefed.social 5 points 1 day ago

The ok symbol is rather temporary but topologically that would count. I wouldn't count pores or membranes here (I mean by my arbitrary definition).

I didnt include them for the same reason I didn't include the ears or the urinairy tract (they're not "holes" as in tunnels, topologically speaking), but if your definition differs from mine then you're right.

They go all the way thru the skin, but not all the way thru the body, so I guess you're right.

Plus a hole for peeing i hope

Peeings over rated

That's topologically not a hole, your bladder like you lung is on the outside/surface.
